cerberus on 2.4.17-rc2 UP

Hi,

I tried out the latest cerberus from
http://people.redhat.com/bmatthews/cerberus/ on a UP redhat-7.2 box. I ran the
standard non-destructive RedHat tests.

It ran for about 14 hours and then became unresponsive..  machine still ping'ed
, I could switch VC's scroll up on console, but that's it. Could not log in,
etc.. Another point is that the hard drive light remained on but it was not
seeking, it seemed dead silent.

Kernel was compiled using redhat's stock gcc-2.96. Unfortunatly, I did not have
sysrq turned on (I just assumed there would be no problem on UP). The machine
is very well ventilated. 

The symptoms sound very much like what Bob Matthews reported on his 8 way...
just that they take longer to manifest themselves.

I'm willing to test/provide more info. The machine is slated for production
soon so I might only have a week or 2. I'm running the tests again now with
sysrq turned on.

Machine has 128Mb, 270Mb swap, IDE, ext3. no DRI or X. stock 2.4.17-rc2 no
patches applied.

Here is dmesg, lscpci, lsmod, /proc/cpuinfo output:

hmmm, maybe that's a data point.. you should forward it to the list.

Can you please run Cerberus again and give me more information ?

I want Alt+SysRQ+T, Alt+SysRQ+M and Alt+SysRQ+P output.

If those keys simply print the sysrq header, please try Alt+SysRQ+8 then
the above again.

Thanks

I did and the machine made it through this time ( in 18 hours). The thing 
is that I skipped the LTP and crashme tests because last time, they 
finished in 8 hours succesfully and the machine only locked up after 14 so 
I thought that one of the other tests that were still running were 
responsible. 

In anz case, I don't have access to the box till thursday due to the 
holidays. I will re-run with all tests then.

Cheers,

ok, I *finally* got it to deadlock again.. trick is to run 2 simultaneous
cerberus runs.. same symptoms, pings, can change VC's, hard drive light
constantly on but silent and no blinks. I had sysrq turned on this time (tested
before the run), but once deadlocked, doing Alt+SysRQ+8, Alt+SysRQ+T, etc would
print nothing at all..
